Document Type and Number:
Japanese Patent JP6046805
Kind Code:
B2
Abstract:
Provided is a speaker device with which high strength can be obtained for the connection between an outer peripheral region of an edge and an attachment part of a frame, even while reducing a size of the speaker device without sacrificing a breadth of a diaphragm and the edge. This speaker device (10, 20, 30) includes: a diaphragm (11, 21) that radiates sound; an edge (12, 22, 32) arranged in an outer periphery of the diaphragm (11, 21); a frame (13, 33) arranged in an outer periphery of the edge (12, 22, 32) and including an annular attachment part (13a, 33a) connected to an outer peripheral region (12b, 22b, 32b) of the edge (12, 22, 32); and an annular connecting member (17) arranged between the outer peripheral region (12b, 22b, 32b) and the attachment part (13a, 33a) and adhered to the outer peripheral region (12b, 22b, 32b) and the attachment part (13a, 33a). A width of the connecting member (17) is greater than a width of the outer peripheral region (12b, 22b, 32b), and an inner diameter of the connecting member is less than an inner diameter of the edge (12, 22, 32).
